This form in addition to being collapsible is-re movable, thereby constructing a cement floor 10 section spanning"between-opposed floor I'- bea-ms entirely devoid of" any, reinforcement, exceptinga-wirefabric or expandedmetalor metal open work on the'und-er surface-of the cement-floor section, saidccment fiooor section including woodchannel beams immediately under the floor I beams, each cement floor section being interlocked with an adjacent floor section at; a point within-the wood channel beam.

Another-feature of theinvention comprises the various stress supporting frames, and after the cementitious material. has thor oughly seasoned andhardened at least sufficiently to retain-the floor section'in position, the stress supportingframes 1 are collapsible, hence easily removed. 1

Still another feature consists inpositioningthe expended 'or-"wire fabric or metal open work at rightangles to the arrangement of similar; material insaid (lo-pending application, in order to-l'caveth-e wire" fabric or expanded metal OFHI QlZiLl open work adjacent the under surface ofthe floor, so that When theflooring is thoroughly set the under surface of the floor (which isreally the celling'of the'room below) may be supplied with additional cementitiousmaterial in order to give the ceiling'the proper finished appearance.

Referringtothe'drawings, 1' identifies "a 1 flooring and ceiling construction comprising the wood forms 3 (which maybe tempo rarily supported. by in 1 any convenient, well known manner such as studd'ing notshown) and the fioorcI-beams .4, the floor channel beain'srbeing between the sh elding 5.. V

In constructingorforming the floor and ceiling of cementitious material stress sup: porting frames Gare provided; These frames consist ofsections'f and 8,. which. are pivotal 1y united on a pin or: bolt 9, there beinga spacing sleeve or tube IObetweenthe piv= otcd'ends of'the sections- The side bars'of the section 7 eachconsist of" two parts 11 and 12,; the former being U shaped, andthe latter being; T-shapedj and s l id'ably or telescopically connected" to; the part 11 with transverseboltsor pinsr'ldand in order to hOlCltllG two parts oflthe's'ection rigidly iii-alignment.

appliance according to ico The section 8 of the stress supporting frame is similarly constructed, therefore the reference characters correspond with those of the section 7. Each of the sections of the stress supporting frames have transverse bars 14:, and in placing the form in position for constructing a floor and ceiling, the side bars ofthe sections 7 and 8 engage on the edges of the adj acentflangesof the wood floor channel beams, while the remote ends of the side bars of the sections 7 and 8 engage with the basis of the floor I-beams, in the-corners where the'basis of the I-beams join with the webs thereof.

In constructing a cement floor these stress supporting frames for temporary use are dis posed side by side, that is edgewise, with the remote ends of the side bars of the sections resting on the basis of the I-beams of the sections with the transverse bars or rods immediately adjacent and resting upon the edges of the opposed flanges of the floor channel beams.

Metal pliable twisted straps orbands or like members 15 engage about thestress supporting frames as shown, and eachincluding a turn buckle 16, so that by turning up on the buckles the bands can be tightened, and thereby support pieces of expanded metal, wire fabric or metal open work, extending the full length of the form, in a direction just at right angles to the positioning of similar material in the co-pending application, This expanded metal or wire fabric or metal open'work 17 is temporarily supported by the bands orstraps, that is until the stress supporting frames are removed, after which it adheres to the under surface of the spanning cement flooring, between opposed parallel floor I-beams. 7

After the stress supporting frames arein position and the bands or straps are applied and tightened and expanded metal positioned the cement is applied and is allowed to mix with similar material in the wood forms 3, so that when the stress supporting frames are removed the cement floor sections are continuous, under the floor I-beams and integrally connects with an adjacent floor section. I v

Afterthe cementitious floo ng thoroughly sets and seasons,the transversebolts of the side bars of the two parts of the sections 7 and 8 are removed, and then by telescoping or sliding-one part of each section within the other. or either sliding one partinto the adjoining ,part of one section the stress'supporting frames may be removed frombe-v tween the'I-beams. Inother words an op- V erationof this kind permits the remote ends .of a the side bars of the stress supporting frames to be detachedfrom engagement with the basis of the I -beams. 1

' Obviously when the frames are so removed the'expanded metal or wireffabric or metal open work remains adhering to the under surface of the floor, providing a means by which the under surface of the floor may be further supplied with cementitious material to construct the ceiling of the room below, said ceiling having a finished appearance as in Figure 4. V r,

It is c stomary in the construction of steel frame work for various buildings to dispose the front, rear and side wall I-beams on a level with the floor'I-beams, but in this particular form for constructing cement flooring it is the purpose, and very essential to lower the front, rear and side wall I-beams just immediately'below the floor I-beams, so that it is possible to construct as air space between the floor areaof one floor of the building and the ceiling area of the floor below, in a manner similar to that in the co-pending application herein previously identified.

It may be that this application does not show how the ceiling area is formed, but it is possible to spanithe V-shaped countersink in the under area of the floor between the floor I-beams in any manner, for instanceby the use of expanded metal or metal open work, and then apply cement plaster'to the expanded metal, and then give a finishing plaster, which may be receptive of wall paper or other cover. In this manner air spaces are provided between the various floor I- beams, and the opposite. ends of each air space. may or may not have louver vents a, which will allow the escape of foul air' from rooms or lavatories, which may not opento the atmosphere at the side, front or rear of the building. V a The wood channel beams are merely for temporary use, that is forthe purpose of constructing cement beams under the floor I- beams, the cement beams 4a, not only rein force the floor I-beams but integrally connect the cement fioorsections between the I- beams, and act to reinforce, therefore it is obvious that when the cement forming the floor sections between the floor I-beams has thoroughly set and seasoned, not only the form is removed but alsothe wood forms. are removed. 1

The expandedmetal or wire fabric or metal open work 17 is formed with up-standing ribs 17a, which imbed in the cement of the floor, which ribs actto reinforce the flooring,

and in addition to provide corrugations 176, which will provide means to retain the finishing cement on the under surface of the floor, provided no air spaces between the floor surface and the ceiling surface are formed.

The invention having been set forth, what is claimed is: i 1. A collapsible form for floor'and ceiling, comprising temporarily vsupported forms which mold concrete .beams, 'I-beams embedded in and supported by said concrete beams, temporary stress: supporting frames consisting of sections united at their adjacent ends, the remote ends of the sections adapted to engage with the lower portions of the I-beams, each section of the stress supporting frame comprising 'slidably united parts including means for holding them rigidly in alignment, means lying over and carried by said stress supporting frames for temporarily supporting cementitious material to form a floor.

2. A collapsible form for floor and ceiling comprising temporarily supported forms which mold concrete beams, I-beams embedded in and supported by said concrete beams, temporary stress supporting frames consisting of sections united at their adjacent ends, the remote ends of the sections adapted to engage with the lower portions of the I- beams, each section of the stress supporting frame comprising slidably united parts including means for holding them rigidly in alignment, means lying over and carried by said stress supporting frames, metal open work on the frames and supported by said last mentioned means, said metal open work adapted to adhere to and support cementitious material to form a floor, and means for adjusting the means carried by the frames, for regulating the positions of said frames, according to the space between the I-beams.

3. In a collapsible form for floors and ceilings, the combination with temporarily supported forms for molding cement beams having I-beams with their lower parts embedded, of a pair of temporary stress supporting frames with their adjacent ends united,their remote ends adapted to engage with the low er parts of said I-beams, said frames diverging toward the I-beams, means lying over said frames and spanning the distance from one remote end to the remote end of the other frame, and including a device for ad- I justing its tension, whereby the positions of both frames may be regulated according to the distance between the I-beams, metal open work supported by said means lying over said diverging frames, said metal open work in turn adhering to and supporting a cementitious material forming a floor or ceiling, the cementitious material encasing the I-beams.

In testimony whereof he afiixes his signature.
